자동차 소재의 미시적 조직 개질에 의한 표면 거칠기 특성에 관한 연구
채왕석(Wangseok Chae),김동현(Ddonghyun Kim),김우순(Woosoon Kim) 한국자동차공학회 2004 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-
In this paper the following conclusions were obtained after examining and analyzing data through the various experiments by engine piston as tile experimental materials among the automobile materials which are being commercialized. The following conclusions all obtained by examining & analyzing the experimental data through machining simulation and machining test through processing test after looking into the variables for interior quality improvement and making two experimental materials by using finite element package; KS AC8B existed already and developed material utilizing the system variable effects. The processing materials are processed on the conditions: spindle speed: 100 rpm, feed speed: 1 mm/rev, and depth of cut: 1 ㎛ and the phase of surface & roughness of the materials are analyzed by 3-D surface analysis microscope(Zygo)As the result of the above experiment, Sample, for example, shows the most excellent surface roughness, P-V 2.382 ㎛, rms 0.137 ㎛, Ra 0.102㎛. <br/> Accordingly, the various data of automobile materials that are examined in this study is judged to be used as the basic references which can help to improve the processing abi1ity, maintaining its own mechanical property when the selection of material and the processing are done at the industrial field.
